WCAG 2.1 Article 3.3.4 (AA)

Hey everyone. Josh here with Online ADA, and in this video we’re covering article 3.3.4– Error Prevention: Legal, Financial Data. This is a AA level requirement, and I’ll jump into the description.

“For web pages that cause legal commitments or financial transactions for the user to occur, that modify or delete user controllable data in data storage systems, or that submit user test responses, at least one of the following is true: Reversible–submissions are reversible. Or, Checked–data entered by the user is checked for input errors and the user is provided an opportunity to correct them. Or, Confirmed–a mechanism is available for reviewing, confirming, and correcting information before finalizing the submission.”

This is the kind of thing that you see a lot when you’re doing online taxes or if you’re doing anything online with a bank that requires multiple forms to be submitted that convey information about yourself. I like the tax, uh example, because that’s one that I’m familiar with personally. You see that online, you’ll see, uh–enter in all of your personal information, all your dependent information, all–your street address, enter in basically all sorts of information about yourself when submitting your taxes. Imagine if we didn’t have any way to correct any mistakes that we’ve made. And what you’ll see a lot of times with these is after you’ve entered a big chunk of data, at the very end of that section you’ll see a review page where you’ll have all that information that you’ve entered with options to edit and make corrections. That’s exactly what this is talking about. That’s a great example of this. You’ve entered a bunch of information and at the end you can review it and confirm–or correct those mistakes if you’ve made any.

This success criterion aims to help people with all sorts of disabilities, all over the spectrum, there. Because people with disabilities, often times when it comes to digital interactions and using these web pages, they’re more prone to making mistakes. So this allows them opportunities to go back and correct those mistakes and it evens it out for them.

Another really good example is a checkout system. We’re all familiar with checkout systems. I’m sure if you’ve ever been on Amazon.com or any other website where you can purchase items, you’ll typically have some sort of cart that you can review. You’ll have multiple pages where you can apply coupons and all sorts of different things. You can modify the contents of your cart and then at some point you’ll be offered a checkout, and you’ll have to enter your payment information. Through that whole process, if you have a chance to review your cart then you are reviewing that– that, uh, this criterion–you’re reviewing your data that you’ve submitted. So you have a chance to correct it or reverse it by, maybe, removing the item from the cart.

That’s really what this success criterion is doing. It’s–it’s basically giving people an opportunity to go back, to make, uh–to change their mind if they’ve made some sort of mistake Okay?

So that’s really all there is for this one. Thank you so much for joining me and we’ll see you on the next one.
